To all whom it may concern:

Be-it known that I, JULIUS UHERKOVICH DE Ummxocz, a citizen of the United States, residing at Bayonne city, in the county of 5 Hudson and State of New Jersey, have, in;

vented certain new and, useful Improvements in Life-Preservers, of which the following is .a specification.

My invention relates to improvements in collapsible bag, expanded by means. of hinged braces or ribs of Wood or other'material within the same, is distended and the bag stretched for thepurpose of holding air.

15 And more especially to those forms of life preservers in which the sustaining power is obtainedby means of air drawn into a hollow body when the'same is expanded, by

means of an 0 en tube which is then closed and theair wit said distendedorexpanded device escapes again as the air-valve is r opened at the will of the operator.

I elect to use in the operation of my device any kind of flexible material for the air bag and for the covering of the same, preferably a cajaiiyaslined with oil or other water-proof coaiiig and impervious to air or water; also any kind of material for the ribs or braces 'within the same, which may be suitable.

The pu ose of my invention is to produce -a-li lit, 0 cap, sure form of device, easily han ed or carried, read .for instant use for sustainin the. body while in the water-and capable o bein compressed into the smallest possible space or the purpose of being carcollapsed position it. appears as s -ried when not in use.

' With this and other objects in view my invention comprises certain novel constructions, combinations and arrangement of 40 parts as'hereinafter molie'particularly described; r F

Figure 1 is a perspective view showing the *invention in position. Fi' 2 is a front view Egrtly in section, said section being taken on 45.

e 22- of Fig. 3. Fig. 3 is" a sectional plan view-taken on'line 3 3 of Fig. 2.- Fig. 41s an enlagged. cross section similar to the section ortion of Fig. 2. Fig. 5 is a plan view 0 my invention showing the device partly collapsed or inflated.

- My invention consists of an elongated circular bag-made of canvas'yor other pliable material, lined with an oil coating or other in which are a series of ribs of wood or otbier stiff material as shown inFi'gs. 2, 3

expanding and.

ribs consisting of two series of members, one series being a vertical brace or rib and the other a series of curved ribs or braces. The end of each rib, that is the verticalrib 1 and the curved rib 2, is covered by an overlapping canvas strip 3 3 and 4 4 respectively as shown in Fig. 4. This over-lappingcanvas is stitched to the outer covering 5 on the. braces 1 and 2. Brace 1 isplaced upright against the curved brace 2 as shown in Fig. 4. Over the outside of brace 1' and brace 2, is stretched the-outside canvas or coveri 5 5 as shown in Figs. 4 and 5. The

hithe body portion -A I havea series of said serles of braces are equi-distant Within the canvas covering as shown in Fig. 3. In

the semi-circular brace 2 there is attached a flexible band of cloth or other material 6 6 and 6, 6 as shown in Figs. 3' and 4. The canvas covering 5 5 is firmly attached to each of the ribs or braces 1 and 2. The ends of these ribs 'or braces form a flexible union at points 7 and8 as. shown in Figs. 2 and 4. When not in use onthe person, the elongated bag is collapsed 'ior'contracted together as shown in Fig. 5-. 'Ateach end of the bag are'the eyelets 9 9'as shown in Figs. 2 and'3.v When the operator desires to use the same he brings the elongated bag around'hls body as shown in Fi' 1, and ties the bag by means of strings as s own in.Figs. 2 and 3. Also attached to the body portion are the shoulder straps 1010 as shown in Fig. 2. When the body portion is untied and is in a partially lie the body portion I have attached a small metal tube 11, with a screw-cap upon the same as shown in'Fig. 2. In the ope'ra-- tion of my device, in order to expand the bag Tpen the tube 11 and pull out the bag to its u length. I then fasten the cap on the tube '11. In this way the air within the ba cannot escape. Having brought the ends 0 the 'now-exp'and' bag around together in circular form and a fastened-themby tying the strings 9 9 we own in Figs. 2 and 3, the circular bag is then passed over the body and the arms passed through the shoulder-straps I0 10as shown in Fig. 1, and the life preserver is then ready for use.

Having thus described In invention what I claim as new and for whic I desire Letters Patent, is as follows 1. A llfe preserver comprising a flexible covering, ribs in the covering arranged in ing the pairs of ribs in spaced relation, an

pairs and the ribs of each pair having their inlet pipe connected to the covering, and 9.

ends flexibly joined by the covering, strips screw cap closure to the pipe.

holding the ribs properl spaced, and strips In testimony whereof I have afiixed my 5 fitted over the ends of t e ribs. signature, in presence of two witnesses.

2. A life preserver comprising a flexible covering, ribs arranged-in pairs in the cover- JULIUS UHERKOVIOH DE UHERKMZ ing and each pair consisting of a straight Witnesses: inner rib and a curved outer rib, strips looped H, T.
